Hello, hopefully someone can help. This is the error i get on my email account on a Mac, i have tried everything to fix it and its driving me mental! Hopefully someone can help! Not sure why it says previous abuse - I literally send one or two emails a week to family and friends!
The sender address xxxxxx@tpg.com.au was rejected by the server mail.tpg.com.au.
The server response was: [TPG-A02] Authentication denied. User xxxxxx@tpg.com.au is banned from using SMTP AUTH due to previous abuse
